Gavin,

	I've never even considered this since I started using Linux, but
as far as installing apps goes since they obviously don't slow the
system down unless in use what about defragmentation. I realize the file
system is different, and I read that it is a journal file system. Does
that mean it organizes itself to prevent fragmentation, or am I missing
a needed bit of maintenance? A bit off topic I know but you spurred my
mind this morning.
